Currently, users in the US can sign up to be part of three health studies: Women’s Health, Heart and Movement, and the Hearing Study. The Women’s Health study uses data from the Cycle Tracking app on watchOS 6. It is aimed to improve the scientific understanding of menstrual cycles. The Heart and Movement Study uses the watch to read movement and health rate information. The Hearing Study, however, examines the impact of sound exposure on hearing health and stress levels.
